we propose a "fast" algorithm for the construction of a data-sparse inver'~ of a general Toeplitz matrix. The computational cost for inverting an N ร N Toeplitz matrix equals the cost of four length-N FFTs plus an O(N)-term. This cost should be compared to the O(Nlog2N) cost of previously published
A look-ahead recumive algorithm for the block triangular factorization of matrices represented as a sum of diagonal and semiseparable ones is derived. This factorization is used for fast solving of the corresponding linear system. For the case of sizes of diagonal blocks not depending on dimension o
